This is my first big piston door so it's not compact at all. It takes a lot of space and is very spread out. SO IT'S NOT COMPACT! It is easy to understand for beginners to start. It is fast closing but slow opening. These type's of door's are hard to get working. It has no bugs and works perfectly fine.

Check out the map to see how this works and enjoy the map!

Please leave feedback to see how I did on it. :)
